SPECEPICATON forming part of Letters Patent No. 355,091, dated December 28, 1886i Application filed July 3, 1885. Serial No. 170.638. (No model.)

To all whom t may concern:

Beit known that we,VoLAv KLN and R-U- Donn SEITZ, both of Prague, Bohemia, Austria- Hungary, have invented a new and useful construction of Improved Sash- Windows with Outside Roll-Shutters, of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved window provided with sliding sashes counterbalanced by weights, which are mounted in such a manner that they can be swung inward on hinges,for the purpose of facilitating the cleaning of the sashes or the repairing of the same.

This invention consists in a window having four sashes-an upper and a lower outer sash and an upper and lower inner sash-all the' sashes being mounted to slide and to swing on pivots, all as Will be fully described and set forth hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Fig. 17 is a detail side view of the hinge-socket piece of the lower `hinge of the inner lower sash. Fig. 18 is a side view of the lower portion of one of the weights carrying the locking device.

A represents the inner upper sash, B the inner lower sash, O the upper outer sash, and D the lower outer sash. The window-frame E Ais provided in its sides with the vert-ical tongues A B D and with the pulley-stile O', i

for guiding the sashes A, B, D, and O, which slide vertically in the frame E. The sashes A, B, and D are provided in their side edges with vertical grooves for receiving said guidetongues A B' D, and through the said grooves the cords by which the sashes are suspended can also be passed. l

The sash cord, chain, and cable F is secured at one end to a hook, F, secured in the groove A2 in the sash A, in that side edge at which the window is to be pivoted to swing-in this case the lefthaud side edge. The said rope or chain F is then passed'over a pulley, F2, at one of the upper corners of the frame-that is, the upper corner on that side of the frame corresponding to the side edge of the sash on which the saine isto be pivoted. It is then passed over the upper part of the face of the frame to and over the pulley F3, at that corner of the frame opposite the one at which the pulley F2 Vis located, from which it is passed down within the casing and secured atitslower end to a weight, F*, which is guided in a vertical groove, ,F5, in one of the side boxes of the frame-in this ease the right-hand side. In a recessed portion of the said weight F4 two crossed levers, F6, are pivoted, the lower ends of which can be passed into notches F7 and F8 in the sides of the groove F5, at the bottom of said groove and at about half the heightof the IOO ing-levers FG are pressed outward-t-hat is, from each other-by the springs F9, secured to the weight F5. Between the upper ends of said locking-levers F6 a cam-piece, G', is mounted on a shaft G, which is pivoted in the weight F and passes through a vertical slot, G5, Figs. 4 and 5, in the piece covering the front of the groove F5, said` shaft being provided at its outer end with a cross-piece or handle, G5, which may be ornamented, more or less.

vIn the piece G5, covering the front of the groove F5,a dovetailed sliding piece, G5, is provided to slide up and down, and said piece is'- provided in its lower part with a longitudinal groove.G"',th rough which the shalt G is passed. 'lhe said sliding strip G5 is provided to cover the slot G2 when the weight F is lowered'.

By turning the handle G3 the cam-piece G' is turned and presses the upper ends of the locking-levers F6 from each other, thereby withdrawing the lower ends f the said locking-levers i'roni the notches F7 or Fand. thereby permitting ofnioving the weight F* up or down through the handle G5,whereby the sash A will be raised or lowered. The lower part of the guide-tongue A', for guiding the swinging edge oi the sash A when the said sash slides, is cut out, as shown at G5, Fig. 1, so as to permit of swinging the free edge-that is, the right-hand edge in this case-o'f the sash from the frame. i

The sash A. will be locked in place when raised, and this is accomplished by the bolt/H, mounted to slide in that side of the frame in which the swinging edge of the sash slides in such a position that it can pass into a notch, H', in the lower part ofthe side edge of the sash A when the said sash is raised. A springH5, presses the bolt H toward the swinging edge of the sash. Said bolt is provided wit-h a longitudinal slot, H5, into which a guide-pin, H4, passes.

An angle-lever, H5, is pivoted in the frame of the window, one shank resting against an end lug of the bolt H and the other end restingon the upper end of a rod, H5, which extends down through the groove F5 behind the weight F, and is provided near its lower end with a lug. H7,- resting on a cam, H", mounted on the inner end of the shaft G, behind the weight, as shown in detail in Figs. 10 and 18. If desired, the angle-lever H5 may be provided in that shank resting against the sliding bolt H with a longitudinal slot, through which a pin passes into the bolt. As the end of the bolt H is pressed against that part of the edge of the sash A above the notch H', said edge is to be protected by means of a metal stri p.

When the sash A is raised, it is locked in place automatically by the bolt H, and the Same movement which unlocks the weight F withdraws the bolt H, to release the said upper sash.

On the left-hand or pivoted edge of the upper sash, A, two hinged plates, I and J, are secured, which are provided with the downwardly-projectinghinge-pins Iand J,of which the pin J' can be passed into the socket J2, fixed on the frame, and the pin I' can be passed into the hinge-socket I2, resting on the top of the hinge-plate J, and mounted to slide vertically on a rod, I3, (shown in Fig. 3,) and secured in the window-frame at that side of the saine at which the pivoted edge of the upper sash is located, so-lhat when said sash A is lowered the lower pin, J', passes into the fixed socket J2, and .the upper pin, I', passes into the sliding socket I2, which slides down with the plate J until it arrives at the lower end of the rod I5, where it is held and prevented from descending any farther. ing socket I2 is lowered as faras possiblethat is, rests on the lower .bent end of the rod I5, fastened to the fraine-the distance between the fixed socket J5` and the said socket I2 will be equal to the distance between the hingepins l and J' on the said upper sash.

When the hinge-pins on the upper sash have been lowered into their sockets, by lowering the sash, the sash can be swung toward theinterior ofthe room, as shown in Fig. 5. When the said sash A is lowered, so that it can be swung out, as stated, the weight F4 is raised and is held in the raised position by the locking prongs F, which are passed into the upper notches, F5, in the sides of the grooves F5.

The lower inner sash, B, Fig. 12, is balanced by means of the weights K, secured to cords .K, passed over pulleys K", Fig. 3, in the sides ,of the frame, the weights K'working up and 4down in the boxes, each of which cords K has its other end secured to aplate, K3, provided with a longitudinal slot, K, and with a longitudinal half-bead, K5, adjacent to and parallel with the slot, which half-bead K5 is mounted to slide in a groove, K5, in the corresponding pulley-stile K7 ofthe frame, said plates K being mounted between the backs of the pulley-Stiles KT and the side edges of the said sash B.

In a recess, L, in the lower part of the pulley-stile a curved lever, L', is pivoted and is provided at its upper end with a hook, L, which can be passed through the top opening, L5, of the plate L", which plate closes the recess or cavity L. The said plate L* is also provided with a bottom opening, L5.

The sash is provided with a groove. B5, for receiving the guide-bead B', and near its lower end with a notch, B5, for receiving part of the plate K5. Y

In the bottom rail of the sash a longitudinal aperture, M, is formed, in which the two sliding bolts M' are mounted, which are connected by the links M2 with the cross-piece M3 on the inner end of the shaft M, mounted When the said slid- IOO to turn in the bottom rail ofl said sash, and

provided on its outer end with a cross-piece or handle, M5, for. turning it. A spring, M", acts on one of the sliding bolts, and thus keeps the ends of both projected from the side edges of the sash, suitable apertured plates,M7,being provided, as shown in Fig. 13, through which the ends of the said bolts are guided. In that end of the aperture or bore M nearest the hinged edge of the sash the link N ispivoted, which has one end connected with the sliding bolt M and the other endv connected with the bolt N, the outer end of which can also be projected from the side edge of the sash.

On the pivoted edge of the sash the hinged plates O and P are secured, from which the pins O' and P project downward, which pins can be passed into the sockets O2 and P5, secured on thewindow-frame. Above the lower hinge-socket, P2, the-piece or half-socket P3 is` passed through a slot in. t-he plate P'i inv such a manner that the said half-socket P3 can pass into and rest on the socket P5, or can be pressed back within the recess behind the said plate P4. Said halfsockeut P3 is connected with a cam-piece, P5, also mounted in a slot in the plate P5, to slide through said slot, said cam having its upper end beveled.

As shown in Fig. 17, the cam P5' and the halfsocket I?3 are on opposite sides ofthe paring bolts pass through the apertures in the,

plates M7 the endof the sliding bolt N' can act on the out-er end of the cam-piece P5, for the purpose of pressing the cani-piece through the slot in the plate P5 into the cavity behind the plate, and thereby also pressingthe half-socket P3 through said plate. In Figs. l5 and I6 the details of the hinges and of the plates or blocks K3 are shown.

The lower outer sash is. mounted in the saine manner as the lower inner sash,andits weights Q are secured to cords, ropes, or chains Q', passed over pulleys Qz in the pulley-Stiles, and having their other endsA secured to blocks Q3, each block being. provided with a haltbead, Q, and with av downwardly-projecting arni,

A Q5, below the haltbead, which arin is provided with a longitudinal slot, Q6.

In the sill-piece R, Fig. 7, of the frame, a recess or slot, R', is for-med for receiving the eX- tension Q5 of each block Q3, one of the said slots or recesses being formed at each side of the" window-frame.

On the bottom cross-piece, R5, against which the bottom edge of the outer lower sash can rest, sliding bolts R3 are provided, one at each side, which can be passed through the slots Q5 ofthe extensions Q5 of the blocks Q3, as shown in Fig. 7,v for the purpose of locking the said blocks in place when the window is to swing. The lowery outer sash, D, is also provided with the sliding bolts M', the shaftM, having a handle, the cross-piece M3, and the links M5, connecting the cr0sspiece with the bolts. The outer ends. of said bolts can pass into notches Q8 in the blocks Q5, thus holding the blocks in placeon the sides of the said lower sash, which sash is provided .with suitable recesses in the side edges for receiving said blocks.

The upper outer sash, C, is connected with a rope or cord, S, which is passed over a pulley, S', at the upper left-hand corner of the frame-that is, at that corner of the frame above the pivoted edge of said sash. Then the said cord or chain S is passed over suitablepulleys in the direction at right angles to the plane of the window to the pulleysv S2 at the inner side of the windowi'raine, Fig. 9, and is connected to a weight, S4, sliding in a groove, S5, constructed the same as the groove F5 in the Window-frame,.but being on the opposite side. The locking device and all other parts on the weight S.4 are the same as those shown Yand described for the weight F4, and consequently there is no necessity of describing. all these'parts'again. The covering-piece for the groove S4 isalso provided with a slot and with a sliding piece, G5, all as stated. In the swinging edge of the said upper sash a notch, T, is provided for receiving the end of the slidingbolt T in the side of the frame, which bolt is pressed into t-he notch by aspring, T5. The inner end of the sliding bolt is connected with an angle-lever, T5, onwhich the 'inner end of the lever T4 acts, which, is pivoted in the side of the casing at right angles to theplane of the window, and with the inner end of this lever the'upper end of a rod, T5, is connected, which is located in the groove S5 in the same manner as the rod F6 is located in the groove F5, and said rod T5' is operated in the same manner from the cani-piece on the shaft in the weight S4 as the rod F5 is operated by a campiece on the shaft in the weight F4,

which construction was fully described here-V inbefore. Said upper outer sash, C, is provided with the two hinge-plates U and V, from which the hinge-pins U and V project downward. At the side ofthe lower pin, V', a campiece, W, is held, which projects above and below the hinge plate, and has its ends rounded. The lower hinge-pin, V', can be passedv into a hinge-socket, V2,1ixcd in t-he casing, and the upper hinge-pin, U', can be passed into the socket U2, which is held on the plate U5 in the side of the casing in such a manner that it can pass in and out. At the side ofv said socket Uz the cam-plate U4 is provided, which has its edge rounded, and on its edges the ends and edges of the canrpiece W and the lower hinge plate, V, can act. The said hinge-socket U2 is provided in its inner part with aslot, U5, through which a guide-pin, U5, passesinto the plate U5, connected with the plate U5. The spring Us presses the said hinge'socket outward, the pin U5in the slot U5 preventing the spring from pressing the socket outward too far.

If desired, all the sashes may be provided in their swinging or in both edges with rollers,

which will cause'them to slide more readily.

on the cross-piece a on the sill. The top crosspiece, b, of thelower inner sash, B, and the bottom cross-piece, c, `of the upper inner sash, A, have their adjacent edges rabbeted, so as to fit snugly against each other. Thetop cross-piece, i.

d, of the upper inner sash, A, is grooved to receive the tongue formed on the top inner crosspiece, e, of the frame.

The bottom cross-piece of the outer lower xsash is grooved to receive a tongue formed on the cross-piece R2 on the sill and the top crosspiece, f, of the outer lower sash, D, and the bottom crosspiece, g, of the outer upper sash, C, have their adjacent surfaces rabbeted to fit snugly against each other. The top cross-piece, h, ofthe outer upper sash is provided witha groove in its top edge for receiving a tongue formed on the outer upper cross piece, k, of the frame.

The window-frame is provided with acrosspiece, m, against which the outer edge of the bottom crosspiece, g, of the upper outer sash, C, can rest when said sash is raised. Adjacent to the inner surfaces of thebottom sashes.

B and D, latches n are pivoted in the w-indowframe in such a manner that they can be swung out to project over the inner surfaces of the side pieces of the lower sashes for the purpose l of guiding the said sashes when they slidevertically.

The guides or stop beads o for the upper outer sash, C, extend `downward only a short distance below the bottom edge of the said sash when the same is raised, asshown i'n Fig. 6, so as not to interfere with swinging the sash.

The operation is as follows: Ordinarily the windows are to be opened and closed by sliding them vertically. 'lo slide the upper inner sash, A, the handle G3 on the shaft G in the weight F, at the righthand side of the window-frame, is turned for the purpose of withdrawing the lower ends of the levers or prongs F from the lower notches, F7, in the groove F5, whereby the weight is released, and at the same time the rofl H is moved upward. and, acting on the angle-lever H5, withdraws the bolt H from the notch Hin the swingingedge of the upper inner sash, A, which is thusV released. The weight F4 is then moved upward by pulling the handle G3 upward, the shaft G on which the handle is formed moving upward within the slot G, and as it moves upward it 'carries upward the sliding piece G5 in the dovetailed groove, which sliding piece serves to cover the slot G6 when the weight is lowered. vTo raise the inner lower sash, B, the handle on the shaft M, Fig. 12, is turned for the purpose of withdrawing the ends of the bolts M', so as to release said sash. The sash can then he moved up and down, the blocks K3 sliding with the sash as they are held in the notches B in the side edges of the sash. As

long as the sash slides said blocks K are not held by the hook-levers L. When the sash is lowered as far as possible it is locked in place by the-endsot' the bolts M', whichA pass into'apertures M in the plates L. Y To raise the outer lower sash, the handle in the middle of the bottom crosspiece is turned for Q of the lower outer sash are secured, are also held in notches in the side edges of the said outer lower sash, so as to slide up and down with the same. ,To lower the outer upper sash,

the shaft G at the left-hand side of the casing is turned'y for the purpose of disengaging the weight S. At the same time the shaft T6 is moved upward, and, acting on the angle-lever rl,by means of the intermediate lever, T,with

draws thegbolt T from the notch in the side of the said upper outer sash. As the weight is raised the sash descends. When the upper, inner, and outer sashes are lowered as far as possible, their weights are locked in p'ace at the proper elevation by the lower ends of the prongs or levers F,which snapl into the notches Ev in the sides of the grooves Ffand S". When the inner upper sash, A, is moved down the upper hinge-pin, I', passes into the sliding socket I2, mounted to slide on the rod I, and said socket and pin descend until the socket arrives at the bottom of the said rod, where it is held. The lower pin, J, passes into the xed socket J". Thre sash'can then be swung toward the interior of the room, as the cord or chain F is connected with the sash at the pivoted edge only, as show n in Fig. 9, and thus does noty interfere with swinging the window out. The sash can be swung out only when lowered, and then only when the hinge-pins are in their proper positions in the hinge sockets. The inner lower sash, B, cannot be swung in the direction toward the interior of the room as long as the upper inner sash is raised, as the top rail, b, of the lower inner sash rests against the lower rail, c, of the npper inner sash when the lower inner sash is lowered and the upper inner sash is raised. When the inner lower sash is lowered as far as possible the upper hinge-pin, O', is in the upper socket, O2, and the lower hinge pin, P', is in the lower socket, P, the half-socket Pa being pressed back into the cavity provided for the same. Before the said sash can be swung out it is necessary for the blocks K, to which the cords or chains K are secured, to be disengaged from the sash and held. To accomplish this the sash is raised and the hinge-pins O and P' partly withdrawn from their sockets until the lower hingeplatein which thelower hingepin, P, is secured has been raised suiciently to permit the spring to press out the halfsocket P3, the pin P resting against the same. Then the shaft M, on which the cross-piece M3 isisecured, and which-shaft is in the bottom cross-piece of the inner lower sash, B, is turned for the purpose of moving the slid- IfO IIO

levers are forced back into the recesses.

ing'bolts M from each other, causing their ends to enter the apertures L5 in the plates L4, and to act on the lower ends of the hook-levers L', pressing said lower ends in the direction from the edges of the sash and thereby forcing the upper ends of said hook-levers through the slots Kof the blocks K3, thus locking the blocks in place. The hooks ofthesaid levers L are held in the slots K4 ofthe blocks K3 against the action of the springs by the weights on the other ends of the cords attached Ito the said blocks. The bolts M are then withdrawn, and the sash can be swung in the direction toward the room. When the sash is swung back into its place in the frame, the handle is first turned for the purpose of moving the sliding bolt N', which acts on the cam-piece P5, connected with and adjacent to the half-socket P3, for the purpose of pressing the said half-socket through the slot, so as to permit of lowering the sash until the hinge-pins O and P are fully in their sockets O2 and P2. By lowering the sashes the blocks K3, which have been passed into their notches B3 in the side edges of the sash B, by swinging the sash back into the frame, are moved downward, and thus are disengaged from the hooks L2 on the upper ends of the levers L', and the upper or hook ends of the The sash is then locked in place by the ends of the sliding bolts M", which pass into the apertures M9.

It is evident that before thelower sashes can be swung outinto the room the latches n (shown in Fig. l) must be swung back. The lower outer sash cannot be swung in the di- 4rection toward t-he room until the lower inner sash has been swung in said direction.

To swing the lower outer sash in the direction toward the room, the handle in the middle of the same is turned for the purpose of withdrawing the ends of the bolts M in the bottom cross-piece of the said lower outer sash from the notches in the casing. Then the sash is raised slightly and the ends of the bolts B3 are passed through the slots Q6 in the extensions Q5 of the blocks Q3, to which the sash cords or chains Q of the said outer lower sash are secured, and thereby the said blocks Q3 are locked in place. The sash can then be swung in the direction toward the room.

Before the upper outer sash, C, can be swung in the direction toward the room it must be lowered, which is accomplished in the manner described. As the sash C descends, the cam-piece W on the lower hinge-plate, V, strikes the rounded edge of the cam-piece U2 connected with the sliding socket U2, and presses said socket into the recess provided for it, so as to permit the sash to pass down. After the campiece W on the lower hinge of the upperouter sash has passed the sliding socket-piece U2, the spring, acting on the said socket-piece, forces the same out, and the upper hinge-pin, U', on the upper outer sash passes into said movable socket U2, and the lower hinge-pin, V, on the upper outer sash passes into the lower socket W. The said upper outer sash can then be swung in the direction toward the room, as the sash-cord does not interfere, the same being secured to or connected with the sash at the pivoted edge of the same. Vhen the sashes, have been swung into the room the panes and frames can be cleaned, repaired, &c.

To bring the sashes back into their normal positions-that is, to adjustthem to slide-the upper outer sash is first swung back into its frame, and is then raised by movingits weight downward. Then the lower sash is swung into place in the frame,and the movable half-sock et of thehingeis pressed back by means ofthe sliding bolt N, which is also provided in the bottom cross-piece of saidouter sash. Then the sash is moved down until its hinge-pins are fully/in their sockets, the bolts R3 are withdrawn from the slots Qin the projections Q5 kon the blocks Q3, in which the sash-cords Q' of the said outer s ash are secured, and the said sash is ready to be moved up and down. Then the inner sash is swung back and adjusted in the manner previously described, and then the c inner upper sash is swung back and raised.

It is evident that our improvements can also be applied on windows having two sashes only-that is, upper and lower sashes.
